Heat Pumps in Sunnyvale: what's different
Heat Pumps work in Sunnyvale follows the local climate. Heat pumps are common in mixed climates and run year-round. Many homes pair them with a gas furnace as a dual-fuel system for the coldest days.
A common Sunnyvale pattern: eichler radiant heat. In-slab radiant systems can leak and need specialized repair, and Eichlers have no attics for ducts, so ductless heat pumps are the usual way to add cooling. Another: gas phase-out. Regional rules make heat pumps the long-term replacement for aging gas furnaces, often paired with panel upgrades.
The heat pumps services Sunnyvale homeowners ask for most are heat Pump Installation. All-electric and dual-fuel systems, sized for your local climate.
The City of Sunnyvale Building Safety Division issues mechanical permits, and California requires C-20 licensed contractors and Title 24 compliance. Silicon Valley Clean Energy has offered electrification incentives.
